1. A method for controlling AC frequency of electrical power being distributed to an electrical distribution network that is connected to one or more electrical loads and to one or more power sources, the frequency control method comprising the steps of:

  • electrically coupling an energy storage sub-system to the electrical distribution network, said energy storage sub-system including one or more flywheel energy storage systems;

    controlling operation of each of the flywheel energy storage systems responsive to total power being outputted by the one or more power sources and a total load imposed by the one or more loads, so the electrical storage subsystem outputs an amount of electrical energy to the electrical distribution network so as to regulate the AC frequency of the electrical power being distributed to the electrical distribution network so as to be at or about a desired AC frequency.
